To all whom it may con c/r22:

Be it known that l. MARTIN Vas: Bun-2x Sm'rn. a citizen of the {'nitcd States of America. and a resident.

of the city county. and State of New York. have inscrubbing or draining proces In carrying out this part of my invention 1 provide a :utpplcmental discharge communicating with the furnace chamber at a.

vented cciain new and useful improvements in (jas- Producers. of which the following is a specification. reference being had to the accompanying drawings. forming a part thereof.

My invention relates to improvements in gas rains. and particularly to apparatus for the manufac' ture of the class of gas known as producer gas.

M y invention consists first in means arranged to produce the distillation of volatile gases from the incotning material prior to its subjection to treatment in the furnace chamber. whereby the lighter more volatile' hydrwcarhons may be available. with the other gases evolved. for use in the regeneratorfurnace. or wherever else the gas is to be employed. .'n the ordinary form of producer the green coal is fed directly to the furnace chambc" where the intense heat destroys a large percentage of the volatile hydro-carbons. which not only and because the volatile ga es have all been evolved before the material reaches the furnace chamber. 1 am enabled to carry off only the stable gases through this supplemental discharge. such gist-s being admirably appadeprives the ill liil product of its full value but causes 2 large deposits of soot to he made. which are deposited in the pipes'and conduits conveying the gas from the producer. In my present invention I have overcome both of these defects by feeding the raw material into the producer in the path of the gases passing from the furnace chamber. but in an opposite direction thereto. distilling out the more volatile gm-ies during the process of so feeding in the material. so that the material. when it reaches the furnace chamber proper. is substantially in the form of coke. Thus it may be said that the coking chamber is arranged as separate and independent from the furnace chamber. The resultant gas is of a better quality. more economical. and richer in heat units. than is the gas generated in tlrordinary gas producers. It will be understood that the gas finally delivered from a producer made in accordance particularly well adapted for certain other purposes.

such for instance as employment as motive fluid in a gas engine. because the lighter hydrocarbon increment t is liable to condensation. .The gas could. of course. he i washed. scrubbed or drained of its non-stable and deposited constituents and then used for any purposes desired lt is a further object. however. of my present invention to provide means id a singte producer for supplying gas not only to rcgcncmtor furnaces. but also to supply gas as motive fluid to gas engines. and that .without necessitating the carrying on of washing.

adapted for the purpose of motive fluid in gas engines. My invention also consists in certain novel features of construction and combination of parts as will hereinafter he more fully described.

In order that my invention may be fully understood, 1 will now proceed to describe an embodiment thereof with reference to the accompanying drawings illus truth-g same. and will then point out the novel features in claims.

In the drawings: Figure 1 is a view in partial side elevation and partial vertical section through an a paratus embmlyiag my invention. Fig. 2 is a view in transverse vertical section of the same along the plane of the line 2-2 of Fig. 1. Fig. 3 is a view in horizontal section substantially upon the plane of the line 33 of Fig. 2. Fig. 4 is a. top view with certain parts removed. Fig. 5 is a view in transverse section through the coking chamber and conduit. Fig. 6 is a detail sec ional view showing particularly the means for feeding in material to the coking chamber.

Reference character 10 designates a gas producer furnace chamber arranged for the reception of fuel tobe burned at a high temperature. The fuel is fed in through the mouth ll of the furnace chamber. and the solid residue after combustion is discharged through ash pits 12. Twyers 13 are provided for supplying the requisite quantity of oxygen in the form of air or otherwise. to support combustion in the furnace chamber, and also to supply steam, if necessary. as is common and w. i known.

Arranged above the furnace 10 at a slight angle from the horizontal. and with one end in open communication with the mouth 11 of the said furnace, is a closed conduit H. the opposite end opening into a vertical down takc 15. which, in turn, leads to a discharge fine 16. 'Rotatably mounted in said conduit it an openended cylindrical shell 17 constituting a coking chamber. rollers 18, and is rotated by means of a. pinion 19 in mesh with a gear ring 20 upon the said shell. The pinion 19 is carried by a shaft 21 driven by any suitable rumins. The coking chamber 17 is arranged dircctly in the path of the gases which rise from the furnace 10, said gases 10 passing through the coking charm her in order to reach the down-take 15 and discharge This shell is suitably mounted upon anti-friction g u) And :1; ans fur npcrzuim: the feed 4 In 1.1mm} 2M spa-mi of rwulutiun of 11g hzunber In :2 uus pic-incur, the combination "with a furnace vizumlwr. and :1 cvuduit in open and dnmrl-uomumnicauon
